Description:
MACHINE FOR FORMING SPAGHETTI

This invention relates to a machine for forming spaghetti.

More specifically, the invention relates to a machine for forming spaghetti especially from carrots, pumpkins, courgettes and the like.

Machines are currently known in the field of machines for forming spaghetti from vegetable products comprising a rotating cylindrical drum with a vertical axis which has, on a relative lateral cylindrical wall, blades shaped for cutting vegetables in order to obtain spaghetti.

In order to obtain spaghetti, for example, from carrots, the drum is supplied from the inside and the carrots, pushed against the lateral cylindrical wall, interfere with the blades which form thin strips similar to spaghetti.

This type of machine has the drawback that in order to obtain long spaghetti it is necessary to provide a large drum, thereby making complex the structure of the machine.

Other traditional machines for obtaining spaghetti from carrots or similar vegetable products cut the vegetable product by means of a relative motion between the vegetable product and a blade resulting in a spiral cutting trajectory along the length of the product.

This type of machine, even though it also enables long spaghetti to be obtained, has a relatively low productivity.

The problem which is at the basis of this invention is to provide a machine for forming spaghetti which allows long spaghetti to be made with a high productivity with respect to the traditional machines described above.

The main aim of the invention is to make a machine for forming spaghetti which is structurally simple, easy to make and easy to use.

Another aim of the invention is to provide a machine for forming spaghetti which achieves a high productivity of spaghetti with a limited overall size. These and other aims, which will emerge more fully below, are attained by a machine for forming spaghetti according to appended claim 1.

Detailed features of the machine for forming spaghetti according to the invention are indicated in the dependent claims.

Further features and advantages of the invention will emerge more fully from the description of a preferred but not exclusive embodiment of a machine for forming spaghetti according to the invention, illustrated by way of non-limiting example in the accompanying drawings, in which:

- Figure 1 is a schematic side view of a machine according to the invention;

- Figure 2 is a plan view of the machine of Figure 1 ;

- Figure 3 is a cross section view according to the line III - III of Figure 1 of an enlarged detail of the machine of Figures 1 and 2;

- Figures 4 and 5 show a plan and perspective view, respectively, of a detail relative to the cutting body of the machine of the previous drawings.

With particular reference to the above-mentioned drawings, the numeral 10 refers to a machine for forming spaghetti its entirety which advantageously comprises:

- a rotating body 1 1 having a cylindrical wall 12 provided with an outer face 13;

- motor means 14 connected to the rotating body 1 1 to rotate it about an axis of rotation A which is central with respect to the cylindrical wall 12.

The machine 10, according to the invention, has a peculiarity in that it advantageously comprises:

- at least one cutting body 15 configured for forming spaghetti and fixed to the cylindrical wall 12 so as to interfere, following a rotation of the cutting body 15 about the axis of rotation A, with products pressed against the outer face 13 of the cylindrical wall 12;

- at least one supply unit 16 provided with a conduit 17 for products to be formed into spaghetti and which has a supply opening C facing the outer face 13; the at least one supply unit 16 comprising supply means 18 for forcing products through the supply opening C and against the outer face 13 so that they interfere against the cutting body 15.

Thanks to this combination of technical features, the machine 10 allows longer spaghetti to be obtained, compared with traditional machines.

In fact, the fact of making spaghetti by pressing the product against the cylindrical wall 12 from the outside of the rotating body 1 1 allows a diameter of the rotating body to be adopted which renders the curvature of the outer face 13 such as to not have negative effects on the length of the spaghetti which can be obtained.

For example, according to a preferred embodiment, the diameter of the outer face 13 is advantageously 700 mm, and, in this case, during use the cutting body 15 interferes with carrots of average length, for example 20- 30 cm, for their entire length, allowing spaghetti to be obtained with high efficiency.

The same applies for forming spaghetti from courgettes or butternut squash.

The cutting body 15 advantageously comprises:

- a series of first blades 19 which protrude from the outer face 13 parallel to one another;

- at least a second blade 20 protruding from the outer face 13 and parallel to the latter.

Advantageously, the first blades 19 are aligned along a direction parallel to the axis of rotation A.

The second blade 20 preferably extends along a direction parallel to the axis of rotation A.

Moreover, the second blade 20 is positioned downstream of the first blades 19 with respect to the direction of rotation of the rotating body 1 1. The cutting body 15 is preferably configured in such a way that, following the thrust of a product against the outer face 13 and a rotation of the rotating body 1 1 about the axis of rotation A:

- the first blades 19 make a series of mutually parallel incisions on the product, and preferably circumferential to the axis of rotation A, and

- the at least a second blade 20 cuts a thin layer of the product at the incisions, obtaining a series of spaghetti from the product.

The cylindrical wall 12 preferably comprises a through operating opening D and the cutting body 15 comprises a plate 21 fixable in a removable fashion in the operating opening D and provided with a passage designed to direct spaghetti, cut by the cutting body 15, through the cylindrical wall 12 towards the inside of the rotating body 1 1. Advantageously for the productivity, the machine 10 preferably comprises a plurality of supply units 16 positioned inside the rotating body 1 1 , preferably at a substantially regular angular pitch about the axis of rotation A.

For example, with reference to Figure 2, in order to keep reduced the overall size, there may be two supply units 16.

The conduits 17 of the supply units 16 preferably extend, for constructional simplicity, substantially radially to the axis of rotation A.

The supply means 18 advantageously comprise a pusher 22 which is slidable in each of the conduits 17 of the supply units 16.

Each pusher 22 is advantageously suitable for pushing products against the outer face 13 of the cylindrical wall 12.

The conduits 17 can advantageously be inclined in order to push, by gravity, the products towards the rotating body 1 1.

The machine 10 advantageously comprises a frame 23 to which the rotating body 1 1 is connected in a rotatable fashion about the axis of rotation A.

The frame 23 is preferably provided with a support 24 defining the axis of rotation A and configured in such a way that, in use, the axis of rotation A is vertical.

More in detail, the motor means 14 preferably comprise an electric motor, advantageously installed above the rotating body.

The support 24 advantageously has a cylindrical seat E which defines the axis of rotation A and the rotating body has a hub 25 which is rotatably housed in the cylindrical seat E, preferably by means of roller bearings 26 or other means for reducing friction.

In order to collect the formed spaghetti, the machine 10 advantageously comprises a hopper 27 which is positioned below the rotating body 1 1 for receiving spaghetti from the latter.

The rotating body 1 1 advantageously has a discharge opening F facing the hopper 27.

The hopper 27 has an internal wall 27a which is substantially conical and coaxial with the axis of rotation A, for centrally collecting to the latter the formed spaghetti.

Advantageously for the efficiency and productivity of the machine 10, the operating opening D advantageously has a first side 28, which is downstream the direction of rotation of the rotating body 1 1 , the first side 28 being inclined, with respect to a radial direction of the axis of rotation A, in such a way as to guide the spaghetti which, in use, are formed, towards the inside of the rotating body.

More specifically, the first side 28 is preferably aligned and substantially parallel to the second blade 20 so as to prevent the spaghetti being formed from being subjected to bending which can cause the breakage.

The machine 10 according to the invention clearly achieves the set aims and objectives.

The invention as it is conceived is susceptible to numerous modifications and variants, all falling within the scope of protection of the appended claims.

Further, all the details can be replaced by other technically-equivalent elements.

In practice, the materials used, as well as the contingent forms and dimensions, can be varied according to the contingent requirements and the state of the art.

Where the constructional characteristics and the technical characteristics mentioned in the following claims are followed by signs or reference numbers, the signs or reference numbers have been used only with the aim of increasing the intelligibility of the claims themselves and, consequently, they do not constitute in any way a limitation to the interpretation of each element identified, purely by way of example, by the signs or reference numerals.
